Laser peening is a proven method for significantly increasing the fatigue life and fatigue strength of metals. The mechanical surface enhancement process utilizes a high-energy, pulsed laser beam to impart compressive residual stress fields into metal alloys such as titanium or steel. Compressive residual stresses add strength and robustness to metal parts by improving their resistance to damage, fatigue, crack initiation, and crack propagation. Laser peening can even be used to arrest the propagation of existing cracks in fielded components, leading to reduced maintenance and repair costs, longer inspection intervals, and significantly increased service lifetimes. Laser peening has been shown to impart beneficial stresses many times deeper than shot peening, leading to increased damage tolerance, reduced fatigue effects, and superior resistance to stress corrosion cracking. Laser peening is routinely applied to turbine engine blades for commercial and military engine components, as well for turbines used in electrical power generation. The process has been employed for years by major aerospace OEMs such as Rolls Royce on its Trent series engines and GE Aviation to improve turbine engine blade resistance to foreign object damage (FOD), fretting fatigue, and cracking. LSP Technologies is the world’s premier laser peening services, technology, and equipment provider. It is the only company in the world selling, installing, and integrating state-of-the-art laser peening systems into manufacturing and research facilities. The Company has been providing laser peening production services for clients in the aviation and power generation industries for over twenty years, and has been awarded more than fifty patents for innovations in laser peening equipment and technology.

The use of laser shock peening (LSP) to enhance the fatigue resistance of metals offers several potential advantages over more conventional surface enhancement techniques such as shot peening, including deeper penetration of the residual stresses, more reliable surface coverage, and the potential for reduced microstructural damage. In the last decade, computational hardware and software resources have advanced to a state that permits numerical simulation of practical LSP processing at a reasonable level of detail, including complex geometric features, multiple and overlapping laser pulses, and intensity variations within the individual laser spots. This article offers some further developments in simulating LSP processes on a realistic scale, as well as some simple methods for distilling and interpreting results from such simulations. A key point of interest is the local variations in residual stress that occur within the processed region, which are quite sensitive to processing variables, and not easily measured experimentally. The simulations suggest that X-ray diffraction measurements of the residual stress field offer only a coarse description of the final residual stress field, and should be interpreted with some caution. We propose some methods for interpreting the simulation results statistically, to provide a clear but accurate characterization of the surface treatment and its effect on fatigue behavior. © 2011 Published by Elsevier Ltd.

Laser peening sytems, for non-medical use.


The invention relates to a method and apparatus for improving properties of a solid material by providing shockwaves there through. Laser shock processing is used to provide the shockwaves. The method includes applying a liquid energy-absorbing overlay, which is resistant to erosion and dissolution by the transparent water overlay and which is resistant to drying to a portion of the surface of the solid material and then applying a transparent overlay to the coated portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shockwave. Advantageously, at least a portion of the unspent energy-absorbing overlay can be reused in situ at a further laser treatment location and/or recovered for later use.

A bend bar is available for use in a quality control test for testing for a consistency of residual stress effects in a particular material using a given a laser peening process. The bar is composed of the particular material to be tested and has a bar length and a bar thickness. The particular material has a characteristic maximum stress penetration depth for compressive residual stresses that can be formed in using the given laser peening process. The bar thickness is chosen so as to be at least twice the characteristic maximum stress penetration depth. The bar has a test surface that extends parallel to the bar length and perpendicular to the bar thickness. After forming a spot pattern on the test surface using the given laser peening process, the deflection generated in the bar due to the compressive residual stresses induced by laser peening can then be measured and used as a quality control measurement.

Composite structures are the future of aviation. They reduce weight and improve fuel efficiency. Composite structures are now incorporated into aircraft by all major aerospace manufacturers. Many composite structures are assembled with fasteners, but, to meet future design requirements, manufacturers need adhesive bonding for their composite structures. In order for the industry to determine the safety and integrity and certify these aircraft, the adhesive bonds in these structures must be tested to verify the manufacturing process and, in subsequent depot level maintenance to confirm they are still adequate. There is no conventional non-destructive testing method available to assure that the bond strength is adequate for service. An inspection technology developed at LSP Technologies, Inc. offers a solution to evaluate the strength of adhesive bonds in bonded structures. This inspection technique is a local proof-testing method that applies a well-controlled dynamic tensile stress to the composite structure and senses inadequacies of these hard-to-detect weak adhesive bonds in response to the tensile stress. The tensile stress is generated by a pulsed laser beam interaction at the surface of the composite material. The controlled local stressing of the composite material has no effect on the material or properly bonded structures.

Existing repair methodologies for cracked structures aboard US Navy ships are currently limited in efficiency and effectiveness. New repair methodologies that directly address the local stress states leading to fatigue cracking and stress corrosion cracking are possible with laser peening technology. The proposed laser peening solution allows repairs independent of the cracked structure geometry, requires no hazardous chemicals, requires no additional NDI, and does not jeopardize the existing structure or corrosion resistance of the material. To demonstrate this materiel solution, proof of concept is demonstrated through a rigorous coupon testing program that replicates in-service cracking conditions and the treatment of these crack conditions via laser peening. Further technology developmental efforts are focused on identifying requirements, options, and an optimal solution for a portable laser peening system design. The laser peening system concept will be designed to meet the key performance metrics for the laser peening process, the size and mobility requirements for shipboard usage, and the hazard mitigation requirements for laser peening in an open environment. The portable laser peening system is anticipated to achieve significant cost savings in comparison to conventional laser peening systems through the use of commercial off-the-shelf (COTS) components.
